9 -Many of the constructs in this layer of the model inherit from the SDMX Base Layer. Therefore, it is necessary to study both the inheritance and the relationship diagrams to understand the functionality of individual packages. In simple sub models these are shown in the same diagram but are omitted from the more complex sub models for the sake of clarity. In these cases, the inheritance diagram below shows the full inheritance tree for the classes concerned with data structure definitions.

Regardless of the position of the //AttributeComponent// within the //DataSet//, the //AttributeComponent// may concern one, more than one, or all Measures included in the DSD. This is expressed using the MeasureRelationship class, which relates a DataAttribute to one or more Measures. Lack of the MeasureRelationship defaults to a relationship to all Measures.
